RCF MB15N351, Mid-Bass 15", 650 Watt RMS / 8 Ohm

This MB15N351 is designed to provide an excellent linearity in the frequency response with low distortion. The transducer is built around a very stronger neodymium magnetic structure and a new 3,5" voice coil, this combination provides to increase the power handling especially in comparison a standard 3" voice coil. The unique Dual-forced air venting system guarantee a very efficient voice coil ventilation for minimize the power compression at the higher power handling.

Features 3.5-inch, inside/outside copper voice coil 1300W continuous program power handling 100 dB Sensitivity 40 Hz - 3 kHz Frequency range Dual-forced air ventilation for minimum power compression Dual spider design with silicon based dampening control
